'!, of the length of the head; the distance across the forehead 
is */, of the diameter. The eye is covered by a thick adipose 
duplicature with a vertically elliptic aperture over the circular 
pupil; it occupies the middle of the distance between the 
muzzle and the posterior margin of the opercle, and borders 
on the profile. The figure of Russell represents the eye much 
too small, probably owing to the adipose fold having been 
overlooked. On the surface of each of the posterior frontal 
bones appear upwards of 11 backwards radiating lines. In the 
individuals examined at Pinang there appeared from six to 
eight teeth in the lower jaw, and some on the palatal and 
pterygoid bones, but none in the upper mavwxillaries, inter- 
mawillaries, nor on the vomer. These teeth are so minute 
that they require to be seen through a lens in dried speci- 
mens, and they are so very deciduous that their number and 
position vary not only individually, but from side to side. 
The .scales of the body are large, rounded, very thin and 
deciduous; those of the back and upper third of the sides 
have each upwards of 16 longitudinal striae. The sides are 
covered by 11 longitudinal series of scales, of which there 
appear to be upwards of 45 in the longest series. There 
are 35 spines on the abdominal profile, the scales of which 
resemble in breadth those of the species of Pellona. The 
greatest vertical diameter of the body, in front of the dorsal, 
is a little less than '/, of the total length. The dorsal occupies 
the middle of the distance between the muzzle and the root 
of the caudal; the fourth ray, the longest, equals the extent 
of the base, which is '/, of the greatest vertical diameter of 
the body. The fin is half covered by an oblique backwards 
rising series of scales which almost hide the last rays. The 
caudal is deeply cleft, the lobes exceed by '/, the length of 
the head. The scaly anal rays are very short; the last slightly 
elongated; the extent of the base is */, of the length of the 
head; its distance from the root of the caudal is '/, of the 
extent. The ventrals are situated opposite the centre of the 
dorsal exactly in the middle between the root of the first 
pectoral and anal rays; their length is '/, of the head. The 
length of the pectorals is */, of the head. At Pinang single 
individuals are of rare occurence. Length: 140 mm.
